俄罗斯环境管理问题所引发的法律思考

对俄罗斯的环境管理观念，相关环境法律规定的生态化要求，联邦及联邦各主体两级关系协调化以及环境管理手段的经济化与多样化倾向等问题作了着重分析，并鉴于中俄在历史上社会与经济制度的关联性及正处经济转轨的共同性，希望通过比较中俄两国在历史和现实发展中存在的异同与联系，以求能为我国进一步的环境管理立法提供借鉴性的思考。     

中国产品生命周期影响评价方法研究

讨论了确定中国产品生命周期影响评价所需的标准化基准和权重的确定方法和程序，包括产品系统环境影响潜值计算，数据标准化，加权评估 以及计算环境影响负荷和资源耗竭系数4个步骤。标准化基准采用1990年中国人均环境影响总潜值来表达，而权重采用1990年的基准与2000年中国政府的削减目标所估算的基准之间的比值计算。

Sustainable resource management coupled to resilient germplasm to provide new intensive cereal–grain–legume–livestock systems in the dry savanna

Sustainable resource management is the critical agricultural research and development challenge in sub-Saharan Africa. The accumulated knowledge on soil management gathered over the last 10 years, combined with solid crop improvement and plant health research at farmers’ level, has brought us to a stage where we can now address with confidence the intensification of cereal–grain–legume-based cropping systems in the dry savanna of West Africa in a sustainable and environmentally positive manner.Two sustainable farming systems that greatly enhance the productivity and sustainability of integrated livestock systems have been developed and implemented in the dry savanna of Nigeria. These are: (i) maize (Zea mays L.)–promiscuous soybean [Glycine max (L.) Merr.] rotations that combine high nitrogen fixation and the ability to kill large numbers of Striga hermonthica seeds in the soil; and (ii) miflet [Eleusine coracana (L.) Gaerth] and dual-purpose cowpea [Vigna unguiculata (L.) Walp.]. Improvement of the cropping systems in the dry savanna has been driven by the adoption of promiscuously nodulating soybean varieties (in particular TGx 1448-2E) and dual-purpose cowpea. The rate of adoption is very high, even in the absence of an efficient seed distribution system. The number of farmers cultivating the improved varieties increased by 228% during the last 3 years. Increased production of promiscuous soybean has been stimulated by increased demand from industries and home utilization. Production in Nigeria was estimated at 405,000 t in 1999 compared to less than 60,000 t in 1984. Economic analysis of these systems shows already an increase of 50–70% in the gross incomes of adopting farmers compared to those still following the current practices, mainly continuous maize cultivation. Furthermore, increases in legume areas of 10% in Nigeria (about 30,000 ha in the northern Guinea savanna) and increases of 20% in yield have translated into additional fixed nitrogen valued annually at US$ 44 million. This reflects, at the same time, an equivalent increase in land-use productivity, and with further spread of the improved crops, there are excellent prospects for additional economic and environmental benefits from a very large recommendation domain across West Africa.

A strategic design approach to develop sustainable product service systems: examples taken from the ‘environmentally friendly innovation’ Italian prize

The product service systems’ (PSS) sustainability potential is described in the framework of the new types of stakeholder relationships and/or partnerships, producing new convergence of economic interests, and a potential concomitant systemic resources optimization.In this perspective, it is argued that the design competencies should move towards those of the ‘strategic design’, thus introducing the concept of ‘strategic design for sustainability’: the design of an innovation strategy, shifting the business focus from designing (and selling) physical products only, to designing (and selling) a system of products and services which are jointly capable of fulfilling specific client demands, while re-orienting current unsustainable trends in production and consumption practices.Some examples of PSS are presented and discussed using the PSS categories ‘services providing added value to the product life cycle’, ‘services providing final results to customers’, and ‘services providing enabling platforms for customers’. The cases derive from an analysis of the ‘environmental friendly innovation’ yearly endowed prize submissions. The Politecnico di Milano University together with the Bocconi University and Legambiente (an environmental NGO) promotes the initiative in Italy.     

中国近海沉积物在生源要素循环中的功能

中国近海沉积物中生源要素的含量与其粒度、河流输入等诸多因素有关。一般沉积物粒度由粗到细 ,有机质含量由低到高 ,OC ,N ,P的含量递增 ,S和Si含量递减。沉积物的生物地球化学环境涉及到Eh ,pH ,温度 ,OC含量 ,Fe3 /Fe2 值 ,水动力条件 ,沉积物的颗粒大小和间隙水的S体系 ,以及生物扰动等因素 ,它们影响着沉积物中生源要素的早期成岩过程和循环。一般而言 ,中国近海沉积物—海水界面S2 -,HS-,H4SiO4,PO43 -,NH4 的扩散通量是从沉积物向上覆水 ,而SO42 -,HCO3 -,NO3 -,NO2 -的扩散通量从上覆水向沉积物中扩散。生物扰动对沉积物—海水界面生源要素的循环起重要作用。
